Benefits of technology

[0016]The invention has been completed in consideration of the above-stated problems in the related art, and an object of the invention is to provide a fuel reformer housing container and a fuel reformer which are capable of maintaining a level of vacuum inside the fuel reformer housing container favorably and which have less power generation loss.

Problems solved by technology

However, the conventional outer wall of the fuel reformer housing container formed into the double-layered structure is not adoptable in the fuel cell system for use in the mobile equipment because the fuel cell system becomes complicated and larger in size overall.
For the fuel cell system for use in the mobile equipment, there has been thus proposed a fuel cell system with a fuel reformer housing container composed of a base having a concave portion and a lid body, of which inner part is formed in a vacuum state to cut off the outward conduction of heat generated in reforming the fuel inside the fuel reformer, resulting in small power generation loss.
In this case, the level of vacuum inside the fuel reformer housing container drops, thus leading an increase in an amount of outward conduction of heat generated in reforming the fuel inside the fuel reformer, with the result that a temperature of the fuel reformer housing container rises by the heat, which may break other components inside the mobile equipment.
In view of the foregoing, the amount of power generation of the heater needs to be increased in order to maintain the reaction temperature, but the increase in the power generation of the heater leads an increase in electric capacity which is used for heating the heater, relative to the total electric capacity generated in the power generation cell of the fuel cell, resulting in a problem that the power generation loss in the entire fuel cell system increases.
